I have been working on improving error handling in my personal tree of lyx-1.1.6fix3... I have already written code which addresses some of these problems, but I have not contributed the patches. Some of the code required a large amount of infrastructure, and as such would not be accepted for a 'fix' release. I plan to port the code to 1.2, but at the moment I am under a lot of pressure to complete a thesis...

I have begun investigating this myself, and can reliably reproduce it - for me, I just navigate around the document while the figures are rendering and usually the rendering queue stops. It's not actually LyX that's stopping the rendering - it seems to be that a ghostscript process is stopping. The problem with the architecture of rendering in LyX is that if one stops, then no more figures are rendered... If anyone has more info on what's going on here I'd appreciate some discussion. I don't know when I'll have time to get all these changes back into LyX, as I have to write furiously. I lost a significant amount of PhD writing time while making the changes, but they seem to work really well now, and are saving me time compared to the old method of searching log files for errors...
